President Vladimir Putin of Russia appears on track to institute a rare tax increase on corporations and high earners, a move that reflects both the burgeoning costs of his war in Ukraine and the firm control he has over the Russian elite as he embarks on a fifth term in office.

Financial technocrats in Putin’s government are searching for new ways to fund not just the war but also a broader confrontation with the West that is likely to remain costly for years. Russia is allocating nearly one-third of its overall 2024 budget to national defense spending this year, a huge increase, adding to a deficit that the Kremlin has taken pains to keep in check.

The proposed tax increase underscores Putin’s rising confidence about his political control over the Russian elite and his country’s economic resilience at home, showing that he is willing to risk alienating parts of society to fund the war. It would represent the first major tax overhaul in over a decade.
